Feasibility of Home-based Preoperative Exercise in Older People

The sessions will be led by a physiotherapist, in the older person's home. The sessions will consist of inspiratory muscle training with a resistance starting from 50% of their maximal capacity (30 breathes, 2 times/day). The training session will also consist of high-intensity individually adjusted functional strength and endurance training: chair-stand; stair climb/step up with weight belts, interval walking indoor and/or outdoor. This will be combined with functional task-exercises. The training will be conducted 2-3 times week, for at least two weeks or until they undergo surgery. During the remaining days, the participants will be instructed to follow the recommendation of 30 minutes of moderate physical activity per day, as well as to perform inspiratory muscle training.
